To all whom, it may concern:

Beit known that I, JOHN H. HUHN, acitizen of the United States of America, residing at Uniontown, in the county of Fayette and State of Pennsylvania, have invented certain new and useful Improvements in Machines for Operating Coal-Angers, of which the following is a specification.

This invention relates to drills, and particularly to that class known as rock-drills.

One object of the invention is to producea drill and its support in which the drill may be adjusted transversely and vertically with relation to the base or support.

Furthermore, an object of the invention is to provide a brace which is movable with the drill-post, whereby the said brace is in position to operate in line with and against the pressure of the drill.

Furthermore, an object of the invention is to produce novel means for affording the adjustment of the post and in provision of novel means for securing the said post in adjusted position.

- Furthermore, an object of the invention is to produce a drill of the character noted which will possess advantages in points of efliciency and durability, proving at the same time simple in construction and comparatively inexpensive to produce and maintain.

lVith the foregoing and other objects in vicw the invention consists in the details of construction and in the arrangement and combination of parts, to be hereinafter more fully set forth and claimed.

ln describing the invention in detailreference will be had to the accompanying drawings, forming part of the specification, wherein like characters denote corresponding parts in the several views, and in which- Figure 1 is a view in elevation from the side, illustrating a rock-drill embodying the invention. Fig. 2 is a top plan view thereof. Fig. 3 is a front elevation with the feed-bar removed and with parts in section.. Fig. 4 is a horizontal sectional view taken on the line 4 4 of Fig. 1. Fig. 5 is a vertical sectional view. Figs. 6 and 7 are a detail view of one of the post-heads. Fig. 8-is a detail view of a bracket for adjusting the post-head. Fig. 9 illustrates a side and end of clamping-plate. Fig. 10 is a view in elevation of a combined sleeve and shaft.

In the drawings, 11 indicates an oil-trap, which may be supported on a motor or any suitable base, and combined guides and supports 12 and 13 are secured to the oil-trap by means of bolts run through the collars 14 and threaded in the bottom of the oil-trap. The guide and support 12 has downwardly-tapered edges 15, and a carriage 16 has a beveled edge fitting against one edge of the guide and support 12. A clamping-plate 17 has its lower portion formed into a Hange 18, beveled to the contour of the opposite edge of the guide and support 12, the said clamping-plate being removable and adjustable through the medium of the bolt 19, run through the end wall of the carriage and threaded in the said plate at the top, which bolt when turned exerts a pull toward the rear on the top of said plate, and the bolts 20, which are threaded in the end wall of the carriage and have their ends seated in the recesses 21 near the lower edge o1' the plate, the said bolts exerting an inward pressure on the lower edge of the clampingplate. Hence it is that between the bolt 19 and the bolts 20 the plate 17 may be made to engage the guide and support 12 in a manner to prevent movement of the carriage except through the manipulation of said bolts.

The sides 22 of the carriage have apertures in which bushing 23 are fitted and a beveled gear-wheel 24 is mounted in one of the said bushings and is driven by the shaft 25, the said shaft being mounted in suitable bearings 26 and the said bearings being supported by bars 27 attached to the two guides 12 and 13. The outer end of the shaft has agear-wheel 28, which is driven through the medium of the wheels 29 30 from the power-driven wheel 31. The wheels 29 and 30 are carried by the arm 32, mounted to partially rotate on the shaft, and the said arm is swung on its pivot by means of therod 33 to cause anengagement and disengagement of the wheels and 31.

A hanger 34 is provided for supporting the.

rod 33.

A stirrup 35a is pivoted on the bushings 23, and a drill-post 35 is supported by and swings with the stirrup. The drill-post has a bushing 36 at its lower end, in which the gearwheel 37 is mounted to mesh with .and take motion from, the gear-wheel 24.` The gearwheel 37 rotates the shaft 3,8, which extends upwardly in the drill-postlaiidlto which is telescopically connected an extension-shaft 39, which latter is journaled in the head A. The upper end of the post is split, and a clamp 40 is applied thereto tosecure in place the internal collar 41. A bracket 42 is bound to the clamp 40 by means of the screw 4 3, and

the said bracket is provided to support the head A in varying degrees of vertical adjustment, as one of said adjustments being shown in dotted lines, Fig. 1.

The head A comprises two duplicate sections having branches a a, each of which carry semibearings for the combined sleeve and shaft b, the said part b having a threaded hole for the reception of the feeding-rod d, the said feeding-rod having a jam-nut e, which may be used, if desired, as a stop to limit the rearward movement of the drill or to bind the drill in the bearing. The combined sleeve and shaft has a toothed flange fmeshing with and taking motion from the wheel g of the extension-shaft 39.

rIhe collar L, secured to the head to move therewith, has a lug` z', to which is pivoted the threaded brace-bar j, the said bar jhaving an adjusting-nut in, against which the sleeve l bears, the said sleeve having a pointed end m, fitting in one of the apertures o, formed in the bottom of the carriage.

Through the medium of the bar j, sleeve l, and the nut 7c the brace may be varied in length in order to vary the position of the drill-post to suit the requirements of the operator, and it will be observed that as the head A is turned from side to side the said brace is carried with it, so that the bracing action thereof will be always in line with the line of action of the drill.

Having fully described the invention, what l claim as new, and desire to secure by Letters Patent, is#
